For those of you who have single-grounded electronics in your guitars, we’re now including a .020 copper grounding strip that's recommended to be installed between the StoneTone Rock Block and your baseplate to counteract any possible grounding issues. A few users have experienced buzz in single-grounded guitars after installing a StoneTone block, especially if the only ground point on the guitar was at the tremolo claw, but were able to easily nullify it by adding this grounding strip. While this isn’t a particularly frequent problem, it is recommended that you install the strip on single and even double-grounded guitars with your block merely as a precaution, so that if you experience buzz or hum after installing your StoneTone block, you or your trusted tech can easily run an extra ground from the tremolo claw ground wire and solder it to the strip, after which your guitar is guaranteed to be quiet. If your guitar is triple-grounded, you can disregard this precaution.
